Subject: Documentation : Update relay function types
X-Git-Tag: v4.19~427^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9ac8c3bd50018c80ad413bff00f054496998cc0d;p=platform%2Fkernel%2Flinux-rpi.git

Documentation : Update relay function types

This patch updates two callback functions provided as an example in
relay API documentation : subbuf_start and create_buf_file_handler.

These functions were using older and incorrect types causing an
"initialization from incompatible pointer type".
